9mm ammo grain question

[Adawg38]

So it's my understanding the lighter the grain the faster and the higher the grain the slower but harder hitting. I've always seen 115gr 9mm was the best but when it comes to target shooting I don't care. I used Corbon 115gr +P for a while. I picked up my new G19 today and wanted to try the Hornady Critical Defense but never really see it anywhere for the caliber I want so I settled for Remmington Home Defense 124gr. I've heard the 147gr wasn't a much desired grain but I took a wild leap and am gonna try it. Blah Blah sorry bout the rammble but my question is what do you guys think about 124gr for home is it better than 115gr?

124's have the highest rating as far as a defense roundin a pistol. The 147's are usually sub-sonic and can be shot through a can pretty quietly. A lot of "cheaper" guns have probelms with the 147's. I belive that the 147's are hard to beat from a carbine as far as 9mm's go.

Therefore I keep 124's in the pistols and 147's in the carbines....

Since the 9mm amm has jumped by leaps and bounds since the 1986 Miami FBI shootout. My belief is that any premium ammo is sufficient by most manufacturers. The Cor-Bon +P used to the the shizzle. I don't feel that it is the best available these days; but not a bad round by a long shot.

115's use usually best left to training ammo as most is FMJ.

Cool! I think you guys hit it. Environment wise Yes I would say wether in the home or on the street I'm thinking face to face I want to make sure it does what's needed and less penetration to avoid hitting any background objects.

Pretty sure I read it here that 147gr rounds can cause problems with your firearm if it's not top of the line. I carry Federal Hydra Shok 124gr in my Glock 17 and Glock 26. I'm not a fan of +p corbon but that's a personal preference.

I reload 124s for plinking/competition and for self defense. Different bullets obviously but the 115s don't always knock down steel and I don't want to use more powder to get the 147s out there because of added recoil and less control.

Not trying to rain on any 9mm parade but the above reasons are why I shoot a 38 Super. For informal plates I like the 124's @ 1100 and can push 147's @ 1200 if need be. Many more options in my case and if you load then the cost of ammo is kind of a moot point.

Just a thought.

I think when you hear about people not being able to cycle 147gr, it is usually because they are using a suppressor. I don't think I've heard of anyone complaining about not being able to run 147 unsuppressed. Could be, I don't know.

Stu, I too have heard the rumors about 147 not being as reliable to feed as lesser weights, but have yet to see this in person.

When I was going through the academy we were using remanufactured 147 grain ammo and i could probably count on both hands how many FTFeed or FTE happened the whole time with all the students. 20 students X 5,000+ rounds = 100,000 rounds fired, and 10+/- malfunctions = 1 in 10,000 rounds had any issues. Of course we were using Glock 17's, so we started with a damn decent pistol in the 1st place.(funny thing is, more math, these were 5 years old. 3 classes a year x 5 years = a possibility of 75,000 rounds through these monsters! and they showed it!!!)

For fun they let us shoot these rounds at 50-75-100 yards. There was 0 hold over needed to get them to hit on target. While it was a total pain in the ass to differentiate between a head shot and a body shot until you walked up to the targets, the steel still made a fantastic noise when you hit it, and the class average was better tha 50% of shots at 100 yards finding steel.

I also have a buddy working for a mountain S.O. that issues him 147gr stuff for his G17. No problems on his end either... Plus being subsonic, there is less chance of him triggering an avalanche!

In conclusion, im a firm believer in the 147gr rounds. I see no problems with them feeding in any modern pistol, and would trust them in any situation.

Throw a baseball, not a tennis ball :-D

So is it correct to assume that the powder charge is relatively equal between all the different grain weights?

Good question... Ive had a couple beers and my roomy wont shut up so i dont have the concentration to compute that data at the moment... :-/

Google says this though!
